使用Jquery实现每日签到功能

基于jquery实现日历签到功能

jquery记事日历插件e-calendar

 

思路:

1、获取当月第一天是周几

2、获取当月共几天

通过获取下月的第0天,即是当月最后一天日期

3、通过二维数组构造当月日历

4、将获取到的日期第一天在日历中展示..

 

知识点:

1、JS获取当月的天数

getDate() 方法可返回月份的某一天,返回值是 1 ~ 31 之间的一个整数。

var d = new Date()

document.write(d.getDate())

输出:17

 

getDay() 方法可返回表示星期的某一天的数字,返回值是 0(周日) 到 6(周六) 之间的一个整数。

var d=new Date()

document.write(d.getDay())

输出:3

 

var d = new Date();

//d.getMonth()+1代表下个月,月份索引从0开始,即当前月为6月时,getMonth()返回值为5,创建日期时同理

 

//此处构造的日期为下个月的第0天,天数索引从1开始,第0天即代表上个月的最后一天

var curMonthDays = new Date(d.getFullYear(), (d.getMonth()+1), 0).getDate();

alert("本月共有 "+ curMonthDays +" 天");

 

2、构造当月日历二维数组

bulidCal : function(iYear, iMonth) {
   var aMonth = new Array();
   aMonth[0] = new Array(7);
   aMonth[1] = new Array(7);
   aMonth[2] = new Array(7);
   aMonth[3] = new Array(7);
   aMonth[4] = new Array(7);
   aMonth[5] = new Array(7);
   aMonth[6] = new Array(7);
   var dCalDate = new Date(iYear, iMonth - 1, 1);
   var iDayOfFirst = dCalDate.getDay();
   var iDaysInMonth = calUtil.getDaysInmonth(iMonth, iYear);
   var iVarDate = 1;
   var d, w;
   aMonth[0][0] = "日";
   aMonth[0][1] = "一";
   aMonth[0][2] = "二";
   aMonth[0][3] = "三";
   aMonth[0][4] = "四";
   aMonth[0][5] = "五";
   aMonth[0][6] = "六";
   for (d = iDayOfFirst; d < 7; d++) {
    aMonth[1][d] = iVarDate;
    iVarDate++;
   }
   for (w = 2; w < 7; w++) {
    for (d = 0; d < 7; d++) {
     if (iVarDate <= iDaysInMonth) {
      aMonth[w][d] = iVarDate;
      iVarDate++;
     }
    }
   }
   return aMonth;
  }

 获取当月第一天是周几:

var dCalDate = new Date(iYear, iMonth - 1, 1);  
var iDayOfFirst = dCalDate.getDay();  

 获取当月共几天:

getDaysInmonth : function(iMonth, iYear){
   var dPrevDate = new Date(iYear, iMonth, 0);
   return dPrevDate.getDate();
  }

 3、构造当月日历HTML

drawCal : function(iYear, iMonth ,signList) {
   var myMonth = calUtil.bulidCal(iYear, iMonth);
   var htmls = new Array();
   htmls.push("<div class='sign_main' id='sign_layer'>");
   htmls.push("<div class='sign_succ_calendar_title'>");
   htmls.push("<div class='calendar_month_next'>下月</div>");
   htmls.push("<div class='calendar_month_prev'>上月</div>");
   htmls.push("<div class='calendar_month_span'></div>");
   htmls.push("</div>");
   htmls.push("<div class='sign' id='sign_cal'>");
   htmls.push("<table>");
   htmls.push("<tr>");
   htmls.push("<th>" + myMonth[0][0] + "</th>");
   htmls.push("<th>" + myMonth[0][1] + "</th>");
   htmls.push("<th>" + myMonth[0][2] + "</th>");
   htmls.push("<th>" + myMonth[0][3] + "</th>");
   htmls.push("<th>" + myMonth[0][4] + "</th>");
   htmls.push("<th>" + myMonth[0][5] + "</th>");
   htmls.push("<th>" + myMonth[0][6] + "</th>");
   htmls.push("</tr>");
   var d, w;
   for (w = 1; w < 6; w++) {
    htmls.push("<tr>");
    for (d = 0; d < 7; d++) {
     var ifHasSigned = calUtil.ifHasSigned(signList,myMonth[w][d]);
     console.log(ifHasSigned);
     if(ifHasSigned){
      htmls.push("<td class='on'>" + (!isNaN(myMonth[w][d]) ? myMonth[w][d] : " ") + "</td>");
     } else {
      htmls.push("<td>" + (!isNaN(myMonth[w][d]) ? myMonth[w][d] : " ") + "</td>");
     }
    }
    htmls.push("</tr>");
   }
   htmls.push("</table>");
   htmls.push("</div>");
   htmls.push("</div>");
   return htmls.join('');
  }

 

4、控件的事件处理机制

指定一个默认的eventName:"load",不同的事件定义不同的eventName

默认时:

eventName:"load",
  //初始化日历
  init:function(signList){
    calUtil.setMonthAndDay();
    calUtil.draw(signList);
    calUtil.bindEnvent();
  },

 

setMonthAndDay:function(){
    switch(calUtil.eventName)
    {
      case "load":
        var current = new Date();
        calUtil.showYear=current.getFullYear();
        calUtil.showMonth=current.getMonth() + 1;
        break;
      case "prev":
        var nowMonth=$(".calendar_month_span").html().split("年")[1].split("月")[0];
        calUtil.showMonth=parseInt(nowMonth)-1;
        if(calUtil.showMonth==0)
        {
            calUtil.showMonth=12;
            calUtil.showYear-=1;
        }
        break;
      case "next":
        var nowMonth=$(".calendar_month_span").html().split("年")[1].split("月")[0];
        calUtil.showMonth=parseInt(nowMonth)+1;
        if(calUtil.showMonth==13)
        {
            calUtil.showMonth=1;
            calUtil.showYear+=1;
        }
        break;
    }
  },

 不同的事件触发:

bindEnvent:function(){
    //绑定上个月事件
    $(".calendar_month_prev").click(function(){
      //ajax获取日历json数据
      var signList=[{"signDay":"10"},{"signDay":"11"},{"signDay":"12"},{"signDay":"13"}];
      calUtil.eventName="prev";
      calUtil.init(signList);
    });
    //绑定下个月事件
    $(".calendar_month_next").click(function(){
      //ajax获取日历json数据
      var signList=[{"signDay":"10"},{"signDay":"11"},{"signDay":"12"},{"signDay":"13"}];
      calUtil.eventName="next";
      calUtil.init(signList);
    });
  }
